Recommended return type for web service that returns nothing (called with jquery)

Question

I have a web service with some methods, they technically do not do much on the client. I call it by jquery / ajax

What is the recommended return type, I would usually return JSON ... but in case it returns nothing ... do I return a boolean? i.e. true = succesful ... and false = error ??

Any ideas?

Answer 1

What about HTTP status codes:

200 OK
500 Error

If it does not return anything, you should use the HTTP status code:

204 No Content
The server successfully processed the request, but is not returning any content.
